The Giant Foundry is a unique Smithing-based minigame in Old School RuneScape that lets players craft massive weapons for giants in exchange for experience, coins, and exclusive rewards. Unlike traditional Smithing, which mostly involves repetitive anvil work, the Giant Foundry adds variety, decision-making, and fun into the mix—making it an excellent training option for players of all levels aiming to level up their Smithing skill.

Whether you're a casual adventurer or a skiller pushing for 99, the Foundry is a valuable tool in your arsenal.

To access the Foundry, you must first complete the Sleeping Giants quest. It's a quick, low-requirement quest that introduces you to the basic mechanics of the minigame and unlocks Kovac weapon workshop, located in the center of the Foundry just south of the Edgeville Monastery.

At its core, the Giant's Foundry tasks players with forging oversized weapons for a giant named Kovac, who commissions you to build blades that meet specific design traits. These traits vary from commission to commission—some may require a spiked or narrow weapon, while others demand a heavy or curved design.

The forging process is not just click-and-wait. Instead, it follows a structured workflow:

1. Accept a Commission-Kovac gives you a detailed request with two required traits.

2. Select a Mold-Choose from a library of molds that best match the desired traits.

3. Fill the Crucible-Melt down 14 metal bars or eligible metal equipment.

4. Pour and Shape-Pour the molten metal into the mold and work on the blade using a series of refining stations.

Each step requires a bit of attention to temperature, timing, and blade condition. Done correctly, you'll create a weapon that closely matches the commission and rewards you with XP, coins, and Foundry Reputation.

Each mold offers a fixed combination of two traits. Matching both traits from the commission gives you a higher blade quality rating, resulting in better XP and bigger payouts. While the mold choice doesn't affect the final stats of the weapon itself, it directly impacts how closely your creation fulfills the commission.

You'll need to combine 14 bars worth of metal—this can be a mix of steel, mithril, adamantite, or rune. Your choice affects how quickly and efficiently you can train:

Steel+Mithril-Good balance for budget-friendly runs.

Adamant+Rune-High-XP, higher-cost setup.

You can even melt down metal gear if it matches a supported bar type.

Once the mold is filled, you'll pass the weapon through a series of stations:

Trip Hammer-Best used when the blade is hot.

Grindstone-Works best at medium temperatures.

Polishing Wheel-Effective only when the weapon has cooled down.

Monitoring the blade temperature is key. Use the cooling pool or lava pit to adjust accordingly and keep your progress bar in the green zone.

Successfully completing a blade earns you:

Smithing XP-Scales with metal quality and commission accuracy.

GP-Coins rewarded for completed jobs.

Foundry Reputation-Used to purchase powerful upgrades.

Top-tier rewards include:

Smiths Outfit-Boosts Smithing XP when worn.

Colossal Blade-A massive decorative weapon.

Double Ammo Mould-Craft two ammo types at once (a money-maker).

Ore Packs-Ideal for Ironmen looking to restock Smithing supplies.

The XP per hour can range from 120k to 250k+, depending on efficiency and metal type used.Level up your game with instant OSRS gold from RSgoldfast. Experience unparalleled quality and customer support - your adventure starts here!
